OPC UA forte Datatype Error [message #1784024]

Hi,

I am trying to go through the tutorials on how to use OPC UA with 4Diac, but I was not able to connect the server running on forte to UA Expert client.
Forte starts without any errors, the app deploys correctly but whenever I try to get connected on the UA Expert interface I get the "Datatype error" and the connection fails with "Bad timeout".

What could be the reason for that? I would be happy if you could give me any recommendations on solving this issue.

I am using the 1.9.0 RC2 4diac and 1.9.x branch of forte.

Thanks,
Kaan

You are connecting to wrong port. Your OPCUA server is listening to the port 4840 (see your image). You should use this port in UA Expert to connect (opc.tcp://localhost:4840), but it seems that you're trying to connect to opc.tcp://localhost:61499. The port 61499 is used to connect with 4diac and load and delete applications and so on.

So:
from 4diac use port 61499
from UA Expert use port 4840

Thanks for the fast reply.

I am still having some connection issues when connecting to the server. It might be caused by the network warnings I added in the attachments.

What is the possible cause of this warnings, how can I fix them?

I don't think those warnings are a problem. What problems are you having now? I see that you're using port 4841 now

This typically happens when one of the FBs in your application is either blocking or taking to long to execute and you have very short E_CYCLES or a lot of network messages.
